Question

Match the thermodynamic processes taking place in a system with the correct conditions. In the table : ΔQ is the heat supplied, ΔW is the work done and ΔU is change in internal energy of the system 

Process	Condition
(I) Adiabatic	(A) ΔW = 0
(II) Isothermal	(B) ΔQ = 0
(III) Isochoric	(C) ΔU ≠ 0, ΔW ≠ 0, ΔQ ≠ 0
(IV)Isobaric	(D) ΔU = 0

(1) (I) – (A), (II) – (A), (III) – (B), (IV) – (C) 

(2) (I) – (B), (II) – (D), (III) – (A), (IV) – (C) 

(3) (I) – (A), (II) – (B), (III) – (D), (IV) – (D) 

(4) (I) – (B), (II) – (A), (III) – (D), (IV) – (C)

Answer 1

(2) (I) – (B), (II) – (D), (III) – (A), (IV) – (C)

Process	Condition
(I) Adiabatic	ΔQ = 0
(II) Isothermal	ΔU = 0
(III) Isochoric	ΔW = 0
(IV)Isobaric	ΔU ≠ 0, ΔW ≠ 0, ΔQ ≠ 0
